The episode as NWS OHX wrote it up.
A line of thunderstorms moved south through Middle Tennessee during the evening hours of August 17, 2024. These thunderstorms were severe when they first entered the area with severe winds downing trees and causing minor roof damage. While they weakened below severe criteria as they moved into the Nashville area, winds were still strong enough to down a few more trees.

Area Forecast Discussion National Weather Service Nashville TN 713 PM CDT Sat Aug 17 2024 ...New AVIATION... .UPDATE... Issued at 634 PM CDT Sat Aug 17 2024 As of 630pm, there were no storm in Middle Tennessee, but a storm over far southern KY had sent a nice outflow boundary down toward Dover and Lafayette. The afternoon has been very hot and very sunny. Thanks to strong subsidence between storms to our east and an approaching front to our northwest, the air has dried out considerably this afternoon with dew points dipping to 60 at BNA while the temperature surged to 99. The low dew points have dropped cape values down below 1000 J/kg, thus no storms and really no clouds. But, a band of much higher dew points and cape values was upstream ahead of the cold front. These greater moisture and instability values will slide into Middle Tennessee over the next couple of hours, and as the front approaches, scattered thunderstorms are expected to develop. HRRR shows this and the NAMNest really blows it up along the front. A few storms could still produce gusty winds and heavy downpours. Unfortunately, the coverage will be lower than we previously hoped, so many people wanting some rain will not get it, and it looks quite dry through the coming week. The best chance this evening will be across the Upper Cumberland. The forecast data was recently updated to reflect the hot temps and low dew points. Also, hourly pops were updated with lower expected coverage. && .SHORT TERM... (Rest of today through Sunday) Issued at 1033 AM CDT Sat Aug 17 2024 A weak upper trough has come through Middle Tennessee already this morning, and there's another one positioned to our immediate west that will come through later on. In addition, a rather pronounced surface boundary will soon begin inching its way across the mid state. Already, the instability needed for additional convection is in place, and the dynamics will be there with the surface and upper patterns being what they are. Most of Middle Tennessee remains under a marginal risk of severe storms today & tonight, with a portion of northeast Middle Tennessee under a slight risk. So the next several hours may be somewhat busy weatherwise, but the activity looks to diminish during the overnight hours, with maybe some lingering cells over the Cumberland Plateau early Sunday. Temperatures tomorrow will be several degrees cooler than today owing the air mass change coming with the fropa. && .LONG TERM... (Sunday Night through next Saturday) Issued at 1033 AM CDT Sat Aug 17 2024 Rain chances after tomorrow will be virtually nonexistent. High pressure will dominate our weather pattern next week, with temperatures hovering below seasonal norms until maybe Friday. Even looking out to 240 hrs., there is only high pressure. So once this weekend's active weather system departs the region, we're headed back into a dry pattern for the foreseeable future. && .AVIATION... (00Z TAFS) Issued at 713 PM CDT Sat Aug 17 2024 VFR generally thru 18/24Z. CSV obs since 17/1853Z, AMD NOT SKED removed. Convection moving thru SE/SC KY. Lightning activity noted, but if SEWD progression continues, low confidence per more stability across our area to mention prevailing shwrs/tstms, mentioned only vcnty shwrs. Convection should dissipate by 18/04Z. MVFR patchy fog formation possible all terminal sites 18/09Z-18/14Z. Shwrs/tstms possible SRB/CSV after 18/18Z, but low confidence prevailing shwrs/tstms, mentioned only vcnty shwrs. && .PRELIMINARY POINT TEMPS/POPS...
